    My tv is about 3 yrs 4 months old. I can hear the audio on it but can not get a picture at all, just black screen. Not even the menu screen pops up for me to switch over to the DVR function.



    Please advise.

Try resoldering the vertical output IC. That may be the problem bad solder has been known to cause that symptom in the chassis

The tv is a Magnavox 51MP392H/17 and has sound but no picture. Any ideas?


TV is in high voltage shutdown protection mode. Check to see if Horizontal output transistor is shorted or open. If not then resolder all solder joints on HV transformer. If this does not fix it then you will need to do voltage checks off of H.O.T. and then possibly a bad HV transformer.

No Sound, No Picture on Magnavox 51MP392H/17


If you hear a constant clicking or chirping sound get the chirping TV repair kit from www.TvRepairKits.com

If you have no video - but have audio - its most likey the HVG.

Note: When the video goes out sometimes its hard to tell if you have audio becuase you can't see the screen to change to the correct channel.

Actually I have this TV and you need 2 Convergence IC's STK392-120's (120's and 150's will work) of course order 2 of the same type I'm using replacement 150's they allow for a little higher heat and were cheaper ALSO you need to replace the 12 resistors with 6.8 ohm metal film resistors, make sure they are metal film! don’t skimp out here I did and then they blew and fried my IC's and I had to replace everything again!

Great reference link that I posted pictures on, check out page 3

Where I got all my parts that worked:
Suburban Electronics http://www.suburban-elect.com/

Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads



What you need:
(2) STK392-120 OR STK392-150 IC chips
(12) 6.8 Ohm Metal Film resistors
set of star screw drivers
15 watt pencil solder pencil, DO NOT use a high watt iron you will fry the surface mounted item.
good leaded solder, and flux


BTW if you don’t plan on trying this and are going to throw out the TV, I still need a IC convergence board for a 51MP392H/17 TV I'm fixing, I'm willing to pay S/H and buy your IC board that’s not been tampered with. Edwinkraus@hotmail.com
